Trever Flume is from our new Dark Times set. The original card had a misspelling, which has been corrected here and on the card list.
Deploying Trever lets you add or remove a credit counter from any unit or Location – an extremely useful ability. You could use it frustrate your opponent if they are using credit counters, or you could use it to gain an extra build point with the “Corridors of Power” card from The Phantom Menace expansion, or gamble with the Lucky Twi’lek Location card. You could also use his ability with Den Dhur (A) or Han Solo (T), both from the Dark Times expansion.
